y
X0 = On: Set the input mode for CH2 to mode 1.
y
X1 = On: Set the Offset value for CH2 to 1V (6,400) and the Gain value to 3V
(19,200).
y
M0 = On: Disable CH2 configuration changes.
3. Program
explanation
y
When X0 = On, set CR#3 to K1 (H’0001),the input mode for CH2 to mode 1 (voltage
input mode).
y
When X1 = On, write K6,400 (Offset value for CH2) into CR#29 and K19,200 (Gain
value for CH2) into CR#35.
y
When X1 goes from On to Off, set M0 = On to disable modifying the A/D conversion
curve. Write K2 (H’2) into CR#40 b1=1.

Adjusting A/D Conversion Curve in Current Input Mode 4, Mode 5 and Mode 6
1. Description
y
CH3 example. When CR#4 is set to current input mode (mode 4), the Offset value
will be set to 0mA (0) and the Gain value to 10mA (10mA/0.625
μ
A=16,000), i.e. input
current -20mA ~ +20mA will correspond to values -32,000 ~ +32,000.
